To all whom it may concern:

Be it known that I, WALTER A, J ones, a citizen of the United States, reslding at C- lumbus, in the county of Franklin, State of Ohio, have invented certain new and useful Improvements in Glass-Drawing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the-invention,such as .will enable others apparatus,

construction January 14, 1913, is elevated to drain the.

skilled in the art to which it appertains to make and use the same.

This invention relates to glass drawing and particularly .to an improved for effecting the draining of a-continuously supplied'drawing pot after each drawing operation.

It has been found in practice that when the draining ring, of the type disclosed in U. S...Letters Patent 1,050,54t granted to me pot the temperature thereof will be materially decreased so that upon reapplication of the ring the glass rising against the inner wall binationof parts to be hereinafter more draining ring elevated.

fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several'views, and inwhich- Fi rel is a 'vert'ical section of a glass tank and'an outworking furnace-with the invvention embodied therein, and Fig. 2, a fragment of what is shown in Fig. 1 with the Referring to the drawings 10 indicates a glass tank and 11 anoutworking furnace disposed adjacentsaid tank. The, furnace 11 is provided with i a removable dome shaped'cover 12 having a central opening 13 therein. Disposed within the furnace 11 is-a drawing pot 14;. which is suitably 0011- nected with the interior of the tank 1O to be continuously suppliedwith molten glass. The mouth of the pipe 1 1 is disposed in line with the opening 13 and the upper end of the wall of said pot is formed by a ring-l5 which extends through the opening 13 and is provided at its upper end with a lateral flange 16 which overlies the cover 12. A suitable hoisting mechanism (not shown) isattached to the cover 12 b means of cables 17 so as to provide for t e elevation of the cover when'desired. The cover 12 is provided with a small opening 18 arranged at one side of the opening 13 for the purpose of permitting heat from the interior of the furnace 11 to escape to the atmosphere when the cover 12 is closed. v

If it is desired to drain the pot 14 it is only necessary to elevate the cover 12. During this elevation of the cover the latter will engage the flange 16 and lift the ring 15 so as to permit the desired draining. When the ring 15 is thus lifted the heat ascending from the furnace 11 will be trapped and directed against said ring by the innerdome shaped wall of the cover and thus provide against the chilling of the rings 15 and the disadvantageous results arising from such chilling when the ring is reapplied by lowering the cover 12 to closed position. If desired the opening 18 can be closed by means of a suitable stopper when the cover 12 is lifted so as to provide against the escape of any heat directly through the cover.

What I claim is 1. The combination'with. a glass tank, of an outworking furnace adjacent said tank, said furnace including a removable dome shaped top provided with a central opening, a drawing pot disposed in said furnace and having" its mouth in line with the opening in the top, means for continuously supplying the pot with molten glass from the tank, a removable ring forming the upper end of the wall of the pot and extending through the opening in the top, and a---lateral flange on the upper end of the ring overlying the cover whereby the elevation of the to will elevate the ring and the inner dome sli wall of the top serving, when the latter is elevated, to catch the ascendin heat and direct same against and throug the ring. 2. The combination of a furnace having a removable dome shaped top provided with an opening, a drawing pot-in the furnace aped having its mouth in line with the opening in vated to catch the ascenamg heat and di- 10 the top, a removable ring forming the uprect same against and through thering.
